Product Brief:

12P3270X032, alias KJ3203X1‑BA1 and VE4001S2T2B4, is legacy Series2 32‑channel dry‑contact discrete input module for Emerson DeltaV M‑series I/O subsystem. It is designed for collecting passive dry‑contact switch signals from field relays, limit switches and auxiliary contacts. No external field power is required for contact detection. It adopts opto‑isolation design to isolate field interference from system backplane. It supports open‑circuit fault detection to report abnormal channel status timely. It supports hot‑swap function, allowing online module replacement without rack shutdown. On‑board LED gives visual feedback of power, channel group running and fault conditions. This is EOL discontinued spare part,widely used for maintenance and renovation of petrochemical and thermal power plant DeltaV DCS equipment. Please confirm hardware revision and rack compatibility before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement.
